  1. She's a runner! Waiting on some special tools to get here as I have some tuning to do on the clutch. Clutch stalls the motor a bit high, so I have a feeling it's all caked with mud in the clutch sliders. Runs good though!
  2. Getting it back together. Engine final mockup and assembly done. Needed to bump the engine to the passenger side about 1/2" to line the CVT up inline with the original location on the old engine. The 670 has a longer crank snout where the pulley seats. Just waiting on some parts for the carb (this setup uses a 1.5mm needle and seat for use with a pulse pump), and the moto carb to stock throttle arm cable,- should be here tomorrow - and we are ready to fire. Starter cranks, all wired up. I only ended up with a kill wire for now, (blue wire from UTV, black/red wire on the motor) , and the starter (white wire ), along with the fused hot wires. Will hook up the oil sending unit from the old engine so I have the oil light.
  3. Thanks Travis! No, this new motor hasn't been fired, lubed everything up well, greased the cam lobes, checked the bearing clearances, will delete the governor arm and mechanism and button it up. Couple more pics.
  4. A few pictures (so far) of the engine work - eventually I will share wiring info and other details (if anyone is interested?) should anyone else ever need to swap an engine in one of these. The replacement engine is a Harbor freight $750 special 670cc, (lawn mower/industrial type lump) with a few minor upgrades. Should have it back together soon, bolted in. The cold weather slows me down!

    Thanks! Haven't taken it apart yet. I was going to prime the oil pump before first before first fire up. I have some parts on the way so I can run a mikuni flatslide carb I have. The stock carb will be too lean apparently.

    Engine Swap Thread

    Small and powerful? Kinda spendy but why not drop a KTM 1290 v twin in it? Will be easier to find parts than a gti lump, water cooled, 100+ HP, chain drive, 6-speed, what more could ya want? Gonna be spendy though, around 3-4K for a wrecker. Any old street bike twin may be good candidate, but many are $$$ and hard to find parts like the gti.

    Should be able to find them online, one for example: http://www.scautosports.com/Massimo_Parts/Warrior_800_massimo/ parts for the 800 warrior anyway. Good luck!

    Current belt is is CVTech JM52-1253-C I guess its not so much power limitation as much as heat control. Gates has their carbon belts that work pretty good in the RZR rigs, so I should be fine. This one is just old, not much wear in 330 hours. May pop for a new belt to go with the motor. Apparently a pretty efficient drive setup.

    So many choices! I did some searches, apparently not many people swap engines in these farm/utility rigs. Golf/club carts ,and go karts, but not these. Another question CVT related, has anyone figured out, or rough idea how much torque the CVTech CVT drive belt can handle? I tried finding info, but im not sure what model this unit is. It looks pretty stout and very little wear in fact. Just wondering how much power I can put to it.

    Yeah I guess you could say these heads are 'screwed' lol No cracks I can see, just a bunch of pock marks from steel chunks beating the pistons and heads. To go with all new parts (heads/pistons) just the parts will be over $500 bucks, so I will try and scrounge some used head cores. I can't even remove one of the plugs it's beat so bad! It's going to take a TON of work to get these decent again. To weld them I need to heat them up pretty hot and may do more damage. I may just cut my losses and go with a new engine, this lump seems to be the red headed step child of industrial v-twin engines, not much to find on it. Will see if I can find a used vanguard engine, or pop for something better. Not sure if there is any demand but I can sell off the good parts of this Subaru engine. Will update when I get something going together. For now I'm just learning what options I have for replacement engines.

    Update: it came off fine, just a few taps with the rubber mallet. Once that was out of my way, I was able to assess the carnage, pretty bad, was not a rod issue as described after all, looks like the screws that hold the air filter housing on rattled into the engine and banged up both chambers, and pistons. Both intake valves had closed on 2 of the screws, other chunks of piston. Not all bad as the case is fine, save for some light scoring that should clean up in one cylinder. The crank, and both rods seem fine, I need to check the intake valves again, both seem like they may be usable, not sure yet. The heads took the brunt of the damage and will cost the most. Pricey parts. Will see if I can get them tig welded and repair the chamber surface as they are pretty bad. Some more pics

    Hi Travis! I think they ran it out of oil. Even though there is fresh oil in it now. Has only 338 hours on it. Mentioned a rod knock and- that they kept using it. I bought it from a guy that works in construction. Didn't get too hot at least. It turned over, but makes clunk noises, when I get the side cover off, the evidence will likely fall into my lap. Paid $1500 for it, seemed like a deal for what we need it for. Just hoping I can salvage what wasn't destroyed. May swap in a Vanguard twin if I need to. I have built many mower and ATV engines over the years, but never this setup.

    The engine manual matches mine, very useful information, thanks for the link. Here is one I found for the CVTech drive: https://americanlandmaster.com/pdfs/UTV/Service/CV Tech Cleaning Procedure (2-20662 & 2-20660).pdf They have the tool, it's a bit spendy, hopefully I won't need it. http://usa.cvtech-aab.com/176-extracteur.html

    Thanks Travis, here is what im working on, I believe it is a CVTech unit. I soaked it good with some PB blaster. Will see what I can do, I don't want to damage it coming off. Do I need to remove the large nut to remove it? I pulled a bolt out before taking these pics. Engine will be out tomorrow, gotta dig my hoist out in the back of the shop. Thanks again.
